AC Not Working? Here are some Common AC Problems

Published on January 30, 2015

Although there are potentially hundreds of reasons why your Niagara Falls home’s central air conditioner may need to be looked at by a certified contractor, there are a couple of reasons that are fairly common. Recognizing what they are may help you to understand what a technician is referring to when they outline the routes for resolving the problem. Here are the top 5 list of problems that may result in a system’s failure. Please review these considerations and determine whether you need to schedule an HVAC inspection.

Faulty wiring

Improper, haphazard or uncertified A/C wiring is dangerous and a possible fire hazard. Bad wiring often prevents the system from getting power or can short the circuit breaker.

Leaking refrigerant

Refrigerant (also known as Freon) is the chemical that cools the air within your air conditioning system. Low refrigerant may suggest a leak or problem with the refrigerant system. If your air conditioning system needs to be recharged with refrigerant, typically that insinuates there is a leak. All refrigerant leaks should be detected and repaired. To read about the phase out of R-22 refrigerant in the United States, we encourage you to visit the U.S. EPA website.

Outside fan is not operating

The fan on your outside AC unit is responsible for conveying the heat from your Niagara Falls home to the outside air. If the fan on the outside unit doesn’t run, proper heat transfer is not taking place and the air conditioning compressor may overheat and trip the safety overload. This action can lead to internal damage to the compressor.

Outside unit not functional

This often indicates a significant reduction of power, contactor problems or even a broken thermostat.

Frozen coil

A frozen coil often indicates trouble with the airflow, such as restrictions caused by filthy air filters or collapsed return air ductwork. Frozen indoor coils could also be the result of low refrigerant.

Best practices suggest that the most effective way for a Niagara Falls area homeowner to prevent these common problems is by participating in a preventive maintenance program. Bad wiring, low refrigerant and airflow problems can be detected during routine maintenance tune-ups. For all these common issues, a professionally qualified, NATE-certified technician can efficiently diagnose the problem area and make the necessary repairs.
